(R,R)-DPEN-modified Ru/gamma-Al2O3-An efficient heterogeneous catalyst for enantioselective hydrogenation of acetophenone

An efficient enantioselective catalyst of 5 wt.% Ru/gamma-Al2O3 modified with R,R-1,2-diphenylethylene-diamine ((R,R)-DPEN) for the hydrogenation of a non-activated aromatic ketone of acetophenone has been investigated, a relatively high enantiomeric excess (ee) of 60.5% was obtained at both the conversion and selectivity larger than 99%, it was about three times higher than the ee values reported up to now for acetophenone hydrogenation with the supported transition metal catalysts modified by chiral reagents. The influences of some reaction parameters such as phosphine ligand, substrate/catalyst/modifier molar ratios, base, solvent, pressure and reaction temperature have been discussed. The chiral modifier of (R,R)-DPEN was very important in controlling the enantioselectivity through adsorption competing with other substrates on the surface of active metal species. The phosphine ligand and base were also important and indispensable in the present reaction.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 2-(Di-tert-Butylphosphino)biphenyl, you can also check out more blogs about224311-51-7

Blue-emitting Ir(iii) phosphors with 2-pyridyl triazolate chromophores and fabrication of sky blue- and white-emitting OLEDs

Heteroleptic Ir(iii) complexes with 3-tert-butyl-5-(2-pyridyl)-1,2,4- triazolate chromophore (bptz) and cyclometalating benzyldiphenylphosphine (bdp) or phenyl diphenylphosphinite (pdpit) ancillary (i.e. [Ir(bptz) 2(bdp)] (1) and [Ir(bptz)2(pdpit)] (2)) are synthesized upon treatment of [IrCl3(tht)3] (tht = tetrahydrothiophene) with the relevant phosphine, followed by the addition of 2 equiv. of bptz chelate at elevated temperature. Their photophysical properties in solution were measured, along with the characteristics detected as dopants in thin solid films. For application, organic light emitting diodes (OLEDs) were also fabricated using 1 and 2 as dopants, achieving respective maximum efficiencies of 17.8% (44.8 cd A-1 and 46.3 lm W-1) and 9.1% (22.8 cd A-1 and 23.6 lm W-1). In addition, sky blue iridium complex 1 was used with red osmium complex [Os(bpftz) 2(PPhMe2)2] (3) to fabricate phosphorescent OLEDs with a sophisticated red/blue/red emitting layer architecture, attaining a stable warm white color with CIE coordinates of (0.397, 0.411). This white OLED attained an electroluminescence efficiency of up to 18.1%, 39.6 cd A -1, and 35.7 lm W-1 for the forward direction.

Anthracene-Bodipy dyads as fluorescent sensors for biocatalytic diels alder reactions

Fluorescence spectroscopy is a powerful, extremely sensitive technique for the investigation of enzyme and ribozyme mechanisms. Herein, we describe the synthesis and characterization of water-soluble fluorescence probes for studying biocatalytic Diels-Alder reactions. These probes consist of anthracene and sulfonated BODIPY fluorophores fused by conjugated phenylacetylenyl bridges. Intact anthracene efficiently quenches BODIPY fluorescence, likely by photoinduced electron transfer. Upon destruction of the aromatic system by the Diels-Alder reaction, the fluorescence emission increases 20-fold. Binding in the catalytic pocket of a Diels-Alderase ribozyme yields a further ?2-fold increase in the fluorescence intensity of both the anthracene-BODIPY and the Diels-Alder-product-BODIPY probes. Therefore, a fluorescence-based distinction of free substrate, bound substrate, bound product, and free product is possible. With these all-in-one reporters, we monitored RNA-catalyzed Diels-Alder reactions under both single- and multiple-turnover conditions down to the nanomolar concentration range. Burst analysis at the single-molecule level revealed blinking of the dyads between an on state and an off state, presumably due to rotation around the phenylacetylenyl bridge. Binding to the ribozyme does not increase the intensity of the individual fluorescence bursts, but rather increases the average time spent in the on state. Variations in the quantum yields of the different probes correlate well with the degree of conjugation between anthracene and the phenylacetylenyl bridge.

Sterically demanding, zwitterionic trialkylphosphonium sulfonates as air-stable ligand precursors for efficient palladium-catalyzed cross-couplings of aryl bromides and chlorides

3-(Di-tert-butylphosphonium)propane sulfonate (DTB-PPS) and 3-(diadamantylphosphonium)propane sulfonate (DAPPS) are air-stable pre-ligands for aqueous-phase palladium-catalyzed cross-coupling reactions. Both DTBPPS and DAPPS were found to give active catalysts for the Sonogashira coupling of aryl bromides at room temperature and 4-chloroanisole at 80 C. These ligands also gave effective catalysts for the aqueous-phase Suzuki coupling of aryl bromides at room temperature.

Discovery of a Potent and Selective Oral Inhibitor of ERK1/2 (AZD0364) That Is Efficacious in Both Monotherapy and Combination Therapy in Models of Nonsmall Cell Lung Cancer (NSCLC)

The RAS/MAPK pathway is a major driver of oncogenesis and is dysregulated in approximately 30% of human cancers, primarily by mutations in the BRAF or RAS genes. The extracellular-signal-regulated kinases (ERK1 and ERK2) serve as central nodes within this pathway. The feasibility of targeting the RAS/MAPK pathway has been demonstrated by the clinical responses observed through the use of BRAF and MEK inhibitors in BRAF V600E/K metastatic melanoma; however, resistance frequently develops. Importantly, ERK1/2 inhibition may have clinical utility in overcoming acquired resistance to RAF and MEK inhibitors, where RAS/MAPK pathway reactivation has occurred, such as relapsed BRAF V600E/K melanoma. We describe our structure-based design approach leading to the discovery of AZD0364, a potent and selective inhibitor of ERK1 and ERK2. AZD0364 exhibits high cellular potency (IC50 = 6 nM) as well as excellent physicochemical and absorption, distribution, metabolism, and excretion (ADME) properties and has demonstrated encouraging antitumor activity in preclinical models.

Synthesis and evaluation of a novel class Hsp90 inhibitors containing 1-phenylpiperazine scaffold

Previously, we identified 1-(2-(4-bromophenoxy)ethoxy)-3-(4-(2- methoxyphenyl)piperazin-1-yl)propan-2-ol (1) as a novel Hsp90 inhibitor with moderate activity through virtual screening. In this study, we report the optimization process of 1. A series of analogues containing the 1-phenylpiperazine core scaffold were synthesized and evaluated. The structure-activity relationships (SAR) for these compounds was also discussed for further molecular design. This effort afforded the most active inhibitor 13f with improved activity in not only target-based level, but also cell-based level compared with the original hit 1.

Living ring-opening metathesis polymerization

Since the discovery of olefin metathesis in the mid-1950s, there has been great interest in using this versatile reaction to synthesize macromolecular materials. More recently, living ring-opening metathesis polymerization (ROMP), a variation of the olefin metathesis reaction, has emerged as a particularly powerful method for synthesizing polymers with tunable sizes, shapes, and functions. The technique has found tremendous utility in preparing materials with interesting biological, electronic, and mechanical properties. This review covers the fundamental aspects of living ROMP and briefly traces its historical development from a catalyst-design perspective. Highlights from the recent literature are used to illustrate the utility of living ROMP in the preparation of macromolecular materials with advanced structures and functions. A discussion on the current status of state-of-the-art catalysts for use in living ROMP reactions as well as opportunities for the future concludes this review.
